SPECIFICATION forming part of Letters Patent No. 596,128, dated December28, 1897. Application filed May 18, 1897. Serial No. 637,119. (Nomodel.)

To all whom it may concern.-

Be it known that I, WALDEMAR SCHEEL, manufacturer, a subject of theEmperor of Germany, residing at Schleusendorf, near Bromberg, Germany,have invented certain new and useful Improvements in Oar-Couplings, ofwhich the following is a specification.

The present invention has reference to an automatic car-coupling whichcan be uncoupled from either side of the cars, thus doing away with thedanger of the man getting caught between the cars while performing theuncoupling.

Figure 1 of the accompanying drawings shows a longitudinal section ofthe bottom of a car, with a view of the coupling parts A and B in place.Fig. 2 shows a top view of the coupling as arranged on either end of thecar. Fig. 3 is a longitudinal section of the coupling parts A and B.Fig. 4 shows the threaded tenon q, the nut r, the worm z, the tenon s,the groove 6, and hole b Fig. 5 shows a section through the tenon q andthe pins b Fig. 6 shows part of the receptacle ol and the drawspring In.Fig. 7 is a vertical section through the cylinder Z,with the channels aand of. Fig. 8 shows a longitudinal section of the tenon q, with thegroove b and the hole b Fig. 9 is avie'w of the drum u with its axle tin section.

The car-coupling is made up of two parts A and B, being arrangedalongside of each other on either end of the car. The coupling-hooks bof the part A are pivotally fastened at c to the tenon cl and areconstantly pressed outwardly by the flat springs a. The noses f, comingin contact with the stops d, prevent the hooks b from opening too far.The cylindrical part 9 of the tenon d rests in the receptacle d and hasa groovei provided around its circumference. A draw-spring is, fastenedwith one end to the receptacle d with the other end to the tenon d andlying within the said groove 1', tends to always keep the coupling-hooksb in the position shown in Fig. 3. The part B consists of a hollowcylinder Z, having two conical rings m n and two slots 0 0, these latterbeing arranged opposite each other and reaching to the foot of theconical ring n. The parts A and B are connected by the cross-piece p,from which branches off the threaded tenon q; The nut a", serving as aworm -wheel, is screwed partly upon this tenon q, partly fits looselyover the tenon s, the latter being fastenedto the bottom of the car. Thenut r engages with the worm z, havin g the axle t. This axle t alsocarries the drum it, upon which the chain w, kept under tension by thespring 1), is wound when the axle t is rotated by the handle 00. WVhentwo cars are being pushed together,the coupling-hooks b slide into thecylinderl and catch in the slots 0 0, thereby coupling the cars. Onecoupling part A and one coupling part B being provided on either end ofthe car a safe and secure coupling is assured.

In case the cars are to be uncoupled the nut r, by means of the handleor and worm z, is rotated,with the efiect of pushing part B farther intopart A. The coupling-hooks b, pressed together by the conical ring n,glide into the channel or groove a, Fig. 3, which latter follows theinner wall of the cylinder Z slantingly for a quarter of a circle. Thehooks b finally reach the bottom of this channel a, and by rotating thehandle a; back into its original position, thereby withdrawing part Afrom within part B, are removed from the channels or grooves aThedraw-spring 7c draws the hooks 19 back again in the position shown inFig. 3. In the tenon q, branching off from the cross-piece 19, twogrooves 17 are provided, being arranged opposite each other-and endingin the holes 5 Figs. 4 and 8. In either one of these holes I) a pin 6Fig. 5, is inserted, which pins reach almost to the lateral edge of thecar-b0ttom.- If the cars are to be uncoupled, these pins b are liftedout of the holes 12 and the threaded tenon q, and thereby the couplingparts A and B are free to be worked.

Having now particularly described and ascertained the nature of myinvention and in what manner the same is to be performed, I

declare that what I claim is-- 1. In a car coupler the combination in acoupling part A of the coupling-hooks b,

ing pivotally fastened on the tenon d, the cy- I lindrical part g ofwhich, having the groove 'i, rests in the receptacle 0?, the spring 70,fastened to the cylindrical part g within the groove 2' and to thereceptacle d said hooksto engage in slots 0, o, in the hollow cylinderlot the coupling part B, the slanting groove outer surface of said nutr, the axle t, the ct, the straight groove a and the two conical drum u,the chain w and the spring 1), the axle 1o rings on and at,substantially as described. 25 to be actuated by the handle 00,substantially 2.
